    c++: defaulted comparisons and vptr fields [PR95567]

    We need to explicitly skip over vptr fields when synthesizing a
    defaulted comparison operator, because next_initializable_field
    doesn't do so for us.

            PR c++/95567

    gcc/cp/ChangeLog:

            * method.c (build_comparison_op): Skip DECL_VIRTUAL_P fields.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/spaceship-virtual1.C: New test.=
